## About the role

Your circuit board will wake up on the lunar surface next year. You’ll design the electronics and flight software that bring our 2027 lunar payload to life: commanding the ISRU brick fabrication process, inflating a habitat bladder, and getting data back to Earth.

## What they're looking for

- Experience designing mixed-signal PCBs from schematic through layout, fabrication, and bring-up (full-cycle)
- RS-485 / serial protocol design: you can write a protocol ICD and define baud rate, framing, CRC, and fault handling from scratch
- Flight software in C/C++ on microcontrollers: state machines, FDIR, watchdog logic, closed-loop control
- Familiarity with spaceflight-adjacent standards for wiring, grounding, and EMI/EMC
- Power electronics: 28 Vdc conditioning, inrush limiting, motor driver integration, and power budget analysis
- Harness design: MIL-STD-38999 connectors, EMI/EMC compliance, thermal-rated wire and insulation (Kapton/PTFE), shielding continuity
